A frayed toothbrush loses its ability to clean effectively. The worn bristles no longer reach between teeth or along the gumline, allowing plaque to stay behind. Over time, this buildup leads to gum inflammation, bad breath, and early gum disease.
Worn bristles also become sharp and uneven, causing micro-scratches on enamel and irritation to delicate gum tissues. Instead of protecting the mouth, an old brush can worsen sensitivity and even push bacteria deeper into the gums.
Dentists recommend changing your toothbrush every 3 months, or sooner if the bristles spread out. A fresh brush ensures effective cleaning, healthy gums, and reduced risk of oral infections.
